This invention relates to improvements in The object of the invention is to provide 7 'a simple and relatively inexpensive device adapted to act as a cushwnmgshackle for buff and draft shocks between vehicles, the arrangement being especially 1 adapted for connection therewith. Fi 2 isa'horizo'ntal sectional view corresponding substantially to I the broken section line 2.2' of Fig.1. And Fig. 3 is a vertical transverse sectional view; correspondlng to the l1ne3-3 of Fig. 1.

In said drawing,"eachof themineicars is" shown as provided with a heavy fioori ng'1 0 and vertical end walls 11. The-flooring 15 cut away to provide pockets 12* at each end of the car to accommodate the partsof the:

shackle. Drawbars are alsoshown on top of the heaw flooringlO, the drawbars being extended outwardly above the pockets 12.-

Cover plates l'are also preferably employed as best shown in Fig. 1, the latter being bolt ed to the flooring. of the car and the drawbars 13.--'

riveted to The improved shackle" ordraftrigging, as shown, comprises, broadly, a yoke A, a second yoke B; a spring C; a block-D; and a second block E, together pling pins FF. I I

The yoke A is arranged in a horizontal plane and has side arms 15-15, and a connecting section 16 at one end; At the other end, the blockE is rigidly secured to the yoke A' by transversely extending rivets 17-17, the block E being vertically aper tured to accommodate the corresponding with theusual cou and fits between, the arms of the yoke A. and also between the arms ofthe yoke B, and is disposedat the opposite end of the shackle to the block E. S id blockD is provided with anelongated "opening 22. through which is;

extended the corresponding coupling F. 7

The spring ;C is interposed-between the block D and the closed end'of the yoke B.

As clearlyshown in Fig.1, the closed "end of the yokeB normally abuts the block E and is perforated'to accommodate the guide lug '23 which is extended from the block E, longitudinally of the device, and which, is

adapted to maintain the yokes Azand B on a common longitudinal center-line. I a 3 With the arrangement. shown, and particu larly as evident from aninspection of Fig. '3, the spring C is substantially completely housed by the four arms of'the twoyokes A and B and is maintained in. proper'posi tion by the arms of said. yokes.

The operation of the device is as follows,

assuming a draft. action, that. is, when the two mine cars are-pulled apart. For convenience of explanation, it may be assumed that the rightha'nd mine carwill remain stationary and that the left hand car moves toward the left- 'as viewed in Fig. 1. .During this draft action, it is evident th'at theyok e A Wlll. be pulled toward the left, thus moving the block D therewith and compressing the spring- C-between the block D and the end 19 of the yoke B, the latter being held stationaryby the coupling pinF on the right hand car. In buifac'tion, that'is, whenthe two cars tend to approach. each other, and still assuming that the' right hand car re mains stationary, the operation isas follows: The yoke A carrying the block E will move toward the right as will also the yoke B. The block D, however, willbe held stationary by the corresponding coupling pin F and hence the spring C will be compressed'between the block D and the end 19 of the yoke B. In addition to cushioning the buff and draft shocks, as above explained, it .will be observed that my improved resilient shackle readily accommodates itself to a pivotal action when the cars are on curved sections of track. i

The device shown and described is'comprised of relatively fewpa-rts, each of which is of simple construction, readily. adapting it for manufacture at small cost. Furthermore, the entire arrangement is such that it may be readily applied to mine cars now in service without any great expense. r I have herein shown and described what I now consider the preferred manner of carrying out the invention, but the same is merely illustrative and I 'contemplate all changes and modifications that come within the scope of the claims appended hereto.

I claim: 7 y

1. In a resilient shackle for mine cars and the like, the combination'with a closed yoke adapted to be attached to the end of one car, said yoke being arranged in one plane; of a second yoke arranged in a plan-e at right angles to the first named plane and looped with respect to the first named yoke, said second named yoke being adapted for slida named yoke to an adjacent car; and a spring disposed between the arms of said yokes and compressible in either buff or draft action.

, 3. In a device of the character described, the combination with two vehicles each having rigidly associated means for attaching va resilient shackle thereto; of a closed yoke pivotally connected to one of said attach-V ing means and adapted to swing in horizontal plane; a second yoke pivotally connected to the attaching means of the other car and adapted also to swing in a'horizontal plane, both of said yokes being movable in the same direction in butting action;

a spring disposed between the arms of said yokes and compressible by said yokes in draft action; and means within said yokes and slidable relativelythereof in buifing action to compress said spring.

I 4. In a resilient shackle for mine cars and the like, the combination with interconnected yokes, one extending in one plane and the other in a plane at right angles thereto; of cushioning means disposed within the arms of said yokes; means for fixedly attaching one end of one of said yokes to one car and limiting its movement with re,- spectthereto to pivotal movement; means for slidably connecting the opposite end of the other yoke to an adjacent car, and means connected with said yokes for compressing said spring upon both buff and draft.

5. In a'resilient shackle, the combination 7 with a yoke; of cushioning means and a follower disposed within said yoke, said yoke and follower belng provided with oppo- I sitely extending alined apertures for the reception of a coupling pin; and an oppositely arranged yoke having a portion adapted to bear upon said follower, and another portion' arranged to bear upon the first yoke, remote from said follower, said last named portion being provided with an aperture for the reception of a coupling pin.

6. In a resilient shackle, the combination with oppositely disposed inter-connected yokes; of cushioning means arranged between the arms of said yokes; and means associated with said yokes operating to compress said cushioning means upon movement of said yokes in unison in one direction and to compress said cushioning means upon movement of one of said yokes relatively to the other.

, In witness that I claim the foregoing I have hereunto subscribed my name this 9th day of August, 1923.
